Game crashes!

I downloaded this level: http://nifflas.ni2.se/forum/index.php?topic=940.0

but when I click on start new game I hear the default cutscene sound (the symbols clashing) and the screen is white but then the game crashes which displays the "Send" / "Don't send" error thing.

It only happens when I start that specific level... weird 

Have you tried reinstalling the level?

Have you tried reinstalling the level?

Yes but it still doesn't work.

EDIT: I checked it in the editor and it seems like it doesn't have an intro Cut-scene. Maybe this is why it crashes.

EDIT EDIT: Nah, I added an intro cutscene...no luck. It still crashes.

Um, I think the problem is mentioned in the thread you linked. Like: It works when you use KSA or remove the custom objects.
So yeah...next time try posting in the relevant level's thread instead of making a new one. Especially when it only happens with that one specific level.

Yeah, I downloaded KSA and it works.
